Adding 401(h) Medical Expense Feature to DB Plan

[JAY21]

Does anyone know if any of the main Volume Submitter Doc providers out there have a Volume Submitter plan w/401(h) post-NRA medical expense "account" language as an optional feature ? We use Accudraft and they said they don't have this as an option within their pre-approved Volume Submitter plan. Would prefer to keep it in the Volume Submitter realm if possible, if not, we'll go the long way via attorney drafted customized plan. We'd be happy to edit a Volume Submitter to include this language and submit as customized plan doc but I have no idea of what language needs to be in there.
